We consider a mutual insurance system whose reserve is determined by a Brownian motion. The controller tries to minimize the total cost by increase or reduce the reserve instantly. Both cases of zero and positive fixed cost are investigated. By applying the theory of stochastic control with QVI approach, we make the connection between singular control and impulse control. The procedures to solve these...
This paper investigates accelerated gossip algorithms for distributed computations in networks where shift-registers are utilized at each node. By using tools from matrix analysis, we prove the existence of the desired acceleration and establish the fastest rate of convergence in expectation for two-register symmetric gossip. Some classes of networks with regular graph topologies are studied in detail...
In the recent decades much research has been performed in order to allow better control of arc welding processes, but the success has been limited, and the vast majority of the industrial structural welding work is therefore still being made manually. Closed-loop and nearly-closed-loop control of the processes requires the extraction of characteristic parameters of the welding groove close to the...
